Hummingbird 200 ESC RaceSpec 80A 3-6S AM32 20x20 Designed for Extreme Racers

The Hummingbird 200 RaceSpec 4in1 ESC is a compact, race-tuned 20x20 ESC engineered for the brutal demands of 5” FPV racing. Developed in collaboration with pro pilot Kyle Buell (Twidgit), it directly addresses real pain points racers face—overheating MOSFETs, pad failures after crashes, and oversized ESCs that don’t fit low-profile frames.

With 80A continuous current for 10 seconds per channel and 100A burst for 3 seconds, this ESC delivers the raw, reliable performance needed to win heats. It supports 3–6S LiPo input, making it perfect for today’s high-throttle 5” race setups.

The board is built on a 6-layer PCB with 3oz copper, blind vias, and a gold-plated finish, ensuring excellent thermal handling and structural durability. Two onboard 400W TVS diodes provide effective surge protection without requiring external components, keeping your build clean and protected.

A standout feature is the 3D motor pad structure—each motor pad wraps around the top, bottom, and side of the board. When properly soldered, this creates a grip-like bond that’s far more resistant to pad delamination, even after hard crashes or broken arms.

Powered by an AT32F421 MCU with integrated gate driver, the ESC runs smooth, responsive AM32 firmware, giving racers reliable performance and open-source configurability in a compact 20x20 footprint.

Whether you’re chasing podiums or rebuilding mid-event, the Hummingbird 200 RaceSpec ESC is built to handle it all—with the performance you need and the reliability you can trust.
